March 31, 2020 - Rex-Cut Abrasives, Fall River, Massachusetts, announces Velocity Mounted Points, a new solution for fast stock removal on small or hard to reach work areas.

Velocity Mounted Points are constructed with a zirconia alumina and aluminum oxide grain blend in a resin bond. These rugged points are suitable for grinding stainless steel and other heat sensitive materials. The premium grain and hard bond blend give Velocity Mounted Points long life and excellent performance on ferrous and non-ferrous metals.

Velocity Mounted Points are the latest addition to Rex-Cut’s popular line of Mounted points and can be used for more aggressive applications such as weld grinding, rapid stock removal, heavy deburring, tool sharpening, and more.

“Our new points remove on average 48% more stainless steel than similar products in the market,” States Bob Costa, President of Rex-Cut Abrasives. “Providing products that minimize time spent grinding welds is our goal.”

Velocity Mounted Points are available in 11 different shapes and 2 different grits.

30 grit: A1, A3, A11, W189, W197, W208, W220, W221, W222 shapes

High-quality ceramic grains provide increased performance

July 10, 2019 - Lawson Products Inc., Chicago, announced the new Blue-Kote™ Soft Material Application Flap Disc, which grinds aluminum and all non-ferrous metals at high speed with minimal clogging or loading, while keeping the work surface temperature low for quality finishing.

The Type 27 abrasive disc is also used with composite materials such as carbon fiber and plastics. The 4.5-inch diameter disc is available in 40 and 60 grit.

Produced exclusively for Lawson Products, the new Blue-Kote Soft Material Application Flap Disc is manufactured from tough aluminum oxide grain layered in a specially engineered net structure. The unique design provides high-performance cut rate and aggressive stock removal with surface blending action for excellent finish consistency. The soft, long-lasting disc that simultaneously grinds and finishes saves process time, eliminates the need for product changeover, and reduces total cost.    

Because aluminum has a much lower melting temperature than other metals, keeping aluminum cool while grinding and finishing is a big challenge for welders and fabricators. The Blue-Kote disc cloth’s net structure resists clogging on soft materials, and its sanded surface stays cooler and avoids burning the work surface.

Blue-Kote Soft Material Application Flap Disc at a glance:

• Specially engineered disc incorporates aluminum oxide grain for excellent grinding combined with smooth, scratch-free finishing and cleaning
• Non-loading
• Grinds cooler than standard discs
• Lasts up to 3X longer than conventional abrasives
• Fewer disc changes required means greater job efficiency and cost savings
• Can be used in pre- and post-weld operations
• Applications and industries include automotive and body shops, agriculture, aviation, construction, energy, food & beverage, metal fabrication, shipbuilding, technology, and mass transportation
• The latest addition to Lawson’s extensive catalog of cutting tools and abrasives solutions

The Lawson Products Blue-Kote Soft Material Application Flap Discs are available now. Lawson Products and Kent Automotive representatives can help users select the abrasive product best suited to their applications.

May 28, 2019 - Titan Tool Supply Inc., Buffalo, New York, announced the introduction of its new line of precision Diamond and Borazon micro-finishing grinding pins. They are designed to meet an increasing demand for small precision ID grinding in industries such as ceramics, electronics, mold-making, and tool-and-die-making. A carbide shank provides added strength and precision, according to Titan Tool Supply.

The working ends of the pins are coated with either Diamond or Borazon. Three diameters are offered for use in small openings. These include 0.016 in. dia. with 500/600 grit; 0.020 in. dia. with 325/400 grit; and 0.024 in. dia. with 325/400 grit.

February 21, 2019 - Weldcote Metals, Kings Mountain, North Carolina, a division of Zika Group, introduced its line of C-PRIME and C-PRIME PLUS ceramic flap discs.

Weldcote’s C-PRIME flap discs feature strong polyester backing for aggressive grinding applications that do not require excessive flexibility. The C-PRIME PLUS flap discs feature an industry-first, poly-cotton backing with high-quality ceramic grain, which provides excellent stretch and flexibility, while adding enough strength to maximize the aggressive cutting points of ceramic grain.

The ceramic grains in Weldcote’s line of flap discs contain a grinding aid for cooler running temperatures, which reduces the risk of discoloration and heat-induced deformations of the final workpiece. These ceramic grains are also self-sharpening, which allow them to be used for longer periods of time than similar flap discs on the market. The C-PRIME flap discs are available in 4 1/2 in. and 7 in. sizes, and the C-PRIME PLUS flap discs are available in 4 1/2 in., 5 in. and 6 in. sizes.

“The C-PRIME PLUS flap discs feature a proprietary compressed design that gives the user a tough edge, increased performance and 50 to 60 percent higher stock removal rates over standard ceramic flap discs,” said Joe O’Mera, CEO of Weldcote. “These increased removal rates can provide significant savings and increased productivity for our customers in the field.”

January 9, 2018 - Weiler Abrasives, Cresco, Pennsylvania, has expanded its offering of small diameter cutting and snagging wheels for high-speed die grinders to include Tiger® AO, Tiger Zirc and Tiger Ceramic. These 2- to 4-inch diameter wheels are designed for long life and fast cutting and join the Wolverine™ value wheels already offered in this category. The 38 item-expansion provides end users in the metal fabrication and ship building industry with increasing levels of cutting performance to meet their needs. Weiler Abrasives will offer the Tiger wheels with 1/4- and 3/8-inch arbor hole sizes.

Weiler’s Tiger AO cutting wheels feature an aluminum oxide grain and provide even, sharp, clean cuts along with a hard bond to extend wheel life when cutting steel. Like the Wolverine wheels, Tiger AO wheels are available in thicknesses of .035, 1/16, 1/8 and 1/4 inch.

Weiler Abrasives is offering its high-performance Tiger Zirc cutting wheels in .035-inch thickness. These wheels feature sharp, aggressive zirconia alumina grains that retain a high cut rate throughout the life of the wheel, making them an ideal choice for cutting steels, including structural and cast iron.

For maximum cutting performance, even on stainless steel and hard-to-grind metals, the Tiger Ceramic cutting wheels provide superior life. The self-sharpening grains reduce discoloration by cutting at lower temperatures with less friction and require less effort to use, minimizing operator fatigue. The wheels are available in 1/16-inch thickness.

December 18, 2018 - Rex-Cut Abrasives, Fall River, Massachusetts, announces the Aluminator, a new solution to Aluminum Grinding that prevents clogging and loading.

Typically when grinding aluminum, bonded wheels overheat the metal causing chips of aluminum to embed right into the grinding wheel, this is commonly referred to as clogging or loading. Eventually there will be no grit exposed, only deposits of aluminum on the face of the wheel. Normally a wax or grinding aid would be necessary to prevent this issue, but that is no longer the case.

Rex-Cut’s new Aluminator T27 Cotton Fiber Grinding Wheel grinds aluminum without any clogging or loading. Cotton Fiber Wheels naturally break down as heat is generated, resulting in constant sharp grit being exposed to the aluminum work piece. This eliminates loading, costly downtime, and the need and expense for wax or grinding aids. The Aluminator offers increased grinding action, greatly improved surface finishing, smooth operator control, and long life. With less noise, less vibration, and safer operating conditions; the Aluminator T27 Cotton Fiber Grinding Wheel is assured to make your Aluminum grinding experience smooth.

“One complaint we hear from fabricators working with aluminum is the need to take extra time to thoroughly clean lubricant residue from work surfaces after grinding. This happens from either grinding aids added to structure of the abrasive product, or waxes used in conjunction with grinding wheels,” states Jon Blake, R&D Manager. “When we designed this wheel, we kept in mind the need for an aluminum grinding wheel that will grind fast and consistent while being 100% lubricant free. This allows fabricators to grind and move on to the next step without stopping to clean their work piece.”

The Aluminator is now available in 4.5 in., 5 in., and 7 in. diameters, in 36 grit.
